Sorry missed the post
No the psu's i own can probably run 2 of the sp20 most are 1600 watt 220v and have over 130 amp each.
The other used psu's are enermax quattro 1200 which are known to be able to deliver 1200 watt continue and they baffled me.
The older 1600 watt psu actually runs handwarm on the casing and the cables, while the older quattro's stay cold as ice on case and cable.
However when the sp20 went down was when it was actually running at start 0.64 and max 0.71 (watt at 288 )
The issue i noticed was that the first sp20 i received actually allways ran fine, bu the new one needed between 0.15 and 0.25 more volts to run same speed.
To avoid power being any issue i tried lower the machine to 0.61 start and 0.66 then all of a sudden the machine was off.
So i tried to power it back on but the lepa 1600 psu refused, so i was thinking of a problem with the psu.
Pulled the reserve 1600 watt recom psu from the rack and put the same machine on that and poof back on running.
Time goes by came back from a job and again machine off, and again psu did not switch back on.
Ofcourse lots of bad language ..... , stupid psu ..... now comes the idiot part i put the lepa 1600 back on this machine poof running again (WTH yes it ran again)
6 hours later i check the miner guess what off again, tested the psu on any other miner i have in the house no go not start.
Let it rest for an hour poof miner runs again on the lepa, so i pulled the quattro 1200 from the antminer c1 and put that on the failing sp20.
Running well for about 3 days poof off, (again alot of bad language) again took another approach pulled my 1000 watt nzxt and the other s3 ant quattro psu (1200watt as well)
So both connected to the sp20 so 2200 watts total can never be a power issue. 5 days later poof off again. and since that it random went off switched between all psu's in the house and once in between a few hours to almost a week it went down again.
Sp support lowered the settings because i had set it to factory default to see if that solved it. and weird enough this far no sudden stop yet.
Still the newer sp20 was needing more voltage to run same speed as the somewhat older one.
Yesterday i  noticed the newer firmware so i installed it instant and since that i also lowered the settings for the miner to alsmot the same as philipma1957 is running his.
My setttings are now 0.616 start and max 0.626 i left the max power at 230 it seems not to matter. The sp1 is still running on the 1200 watt quattro and the sp2 has again his evga 1600g2.
So if i look at the power on the wall both should be able to run on even 1 antec 1200 watt quattro because both pull 565 watt max now
What strikes me is that with the new firmware the machine do about 1000 Gh, but it probably will go up in time.


Before you ask the same psu's have been running other machines for instance 2x ant s3 or c1 or some scrypt rigs and never fail, not even went down a minute in months.
If i switch them between sp1 and sp2 they run perfect on the sp1 but the second ... yes the weird power downs. the quottra pro i pulled from my gpu rig runs months in a row never went down at all. 1 hour on the sp2 poof off and refused to start for at least 30 minutes

Lets hope the weird one will keep running it keeps running now , time will tell

I am not sure what miners you are talking about, but as far as i know they are just a shop which orders from other companies who make a deal with them to sell miners.
Never seen them have own brand miners in shop.
I think you ordered one miner which probably was from a company which disappeared.
Their are plenty which was going to deliver in feb. but went offline or never answer if you mail them

I am not sure but this card runs proper on all ccminer50.exe files, but its not indeed not a new maxwell its the CK110 gpu

ahh only maxwell this version
wait are you sure the other ccminer 5.0 runs perfect

lol

i just wanted to ask whats going on
have tried starting 25 times with -i between 2 and 18 not starting

after new case and better cooling i might test full speed its limited to run maximum temp of 70c now
pretty darn good speed already with so much limits
oops lol different ccminer
lol
the new 39 crashes

I am glad to see i am not the only one having a miner going down without any reason, however in my case my psu switches off and only starts after i have let the psu without power for some time.
I will try the sd card option as well
Also noticed since zvisha set it very low speed it seems to run a bit longer now, really hoping it not again to stop
I does not matter which psu i use all the heavy ones or even a 1000watt and a 1200 watt connected with the weird sp20 it can run for a few hours or a few weeks and then all of a sudden poof its no longer running.
However i am not sure if its the same problem, this machine does need much more power than the earlier bought one.

Thank you sir very nice and complete guide, very helpfull especially for such a old geezer like me who forget todo some things like install the needed packages and constant grumbles when he forgot anything again

I do like the looks now for me better improve the coin with some actions to get the coin to be more popular.
Just changing the looks does not work in my opinion

Office 2013 would be nice to have anyway need to know is these really are retail keys
I need 2 win 8.1 pro keys, are these english language or are you selling others
I do not wanna mess with a russian key again

I can not see proof yet for a scam, but yes most companies suffer from the low btc price.
Their business model is not completely open and i respect that, some agruments look suspicious but this far i am absolutely not complaining.

Several so called legit ones left us with worthless shares being ended premature or shut down cloud products example :  cex, zeushash, genesis, am, zenminer all of them took the cloud mining partially off or pay alot less than we wanted some charged fees which actually ended me paying them for mining.

Hell even mining at cheap locations is going to hurt if you do not have sub 0.06 dollar energy prices.

Not all of it is a scam even though it hurts us who bought into them, ofcourse i get angry too but after a while i do not think all are being bad boys

I see the massive attacks on the guy from pbmining, yes i also lost some btc from them but I DO NOT AGREE PEOPLE attack the person behind it

Why do i say that because i still get paid some fairy dust from the pbmining. How he did it is not important the pbmining failed because btc value is too low to pay the bills of the miners.

Did he had a scam going i am not sure, so stop the witch hunt or keep it straight and correct.

So claim something about the site and they provided info you do not trust, that on itself is not enough proof for me that they are going to scam me.

If cloudminr.io is a bad business model i will find out but this far i am very satisfied and see my weekly pay coming in pretty on time.

Will it make ROI i have to wait till my 5 Th pays off, the only risk is that if the german brothers make true what they posted btc will get another huge hit if 300 to 600  PH enters the btc arena
And do you know what scares me more is that i kinda already know these guys are able todo it if they go online with the machines they are testing.

How do you think thats gonna effect the btc market ... seen what happened with ltc with those massive 1 to 2 Gh scrypt boards indeed down the drain....

On topic if you underclock them and have a cool ambient temperature, you can set the sp20 at fan speed 20 ( normal set at 80 )
The difference between 20 and 80 is huge, i think the noise is now around 72 db
With the fan at 80 it sounds like a small airplane
At startup it goes full speed maybe someone with a good camera can record that
Its ofcourse still audible but absolute a lot less, it seems someone cut the metal in front of the fan away and that made a huge difference in noise as well

Agreed on that yes they cost often more than the psu cost at least the ones being sold each time being replaced.
Our firm replaces the psu's almost every 2 years just to make sure, the ones coming out of these server will work many years flawless, hell i had one for almost 11 years and it still works.
Ofcourse with the much higher efficiency its ofcourse wise to replace them from silver or lower into the better ones.
But i found out some of them rated being 80+ silver (ibm and antec) still beat my brand new platinum psu's
Back on the breakout boxes they do work pretty nice especially the heavy psu models they can feed so many smaller miners its almost insane
My mate uses 2000BB psu's to feed his scrypt-n/x (11,13,15) gpu rigs if you see all those cables coming from just one psu you think omg what!!! all those on 1 psu.
And it all looks nice and tidy with the breakout box

Ran into a weird problem with the Coinspool
I started to follow the get started and instant ran in a problem with the so called key
This mining key makes it possible to create a wallet address which i should be able to import into the program.
But as soon as i put in the import it ends in :
Invalid private key (code -5)

I can rather mine at a pool but somehow i can not get it to work
Mining with your local wallet address fails on the pool and does not record shares

joined address provided a few post before this one

LoL if i own gold i my country i pay tax when i buy it and tax over the tax and if i dare to sell gold i pay tax to sell it, if you got more than a certain amount to sell you pay 70% income tax as well

blade psu's are very capable ones although i see this are very slim models.
The IBM BB psu's are much bigger but often lack cooling but can cope with insane loads
These are made to be cooled by the airflow in the blade servers, a mate and i tested the max load which is a 2800 watt IBM Blade PSU (2980 W - IBM BladeCenter H (7989, 8852)) could handle
We stopped at about 3500 watt load because going higher would be no longer safe, at this extreme load it becomes a huge risk and fire hazard.
But the psu did not even fail once.
These need some adjustments to get them cooled and you need to get the cables soldered, or try to get some tech wiz to create a breakout box for these monsters
Side note when we turned it on the lamps in barn dimmed, so these are not for the faint hearted.
DO NOT USE these without making sure everything can handle these loads.

BlownCoin sounds much better

wow 14300 drk holy mother earth, i got only 24 drk
